Median temperature anomaly from the 30 year average temperature (1961-1990) from 1850-2019. The blue line represents the average annual temperature trend through time, with upper and lower confidence intervals shown in greys.

In 2015-2019. global average temperature was 0.71 degrees Celsius greater than the average temperature between 1961 – 1990.
